My invention relates to improvements in coke ovens, and more particuarly to ovens provided with a frame for pressing a packing medium into aga provided between the ,door and the frame t ereof. The object of theimprovements is to provide an oven of this packing medium is pressedinto the gap by means of pressing members provided with means forslmultaneous operation from one part of the oven. With this object inview my invention consists in the matters to be described hereinafterand particularly pointed out in the appended claims.

In the accompanying drawings,

Fig. 1, is an elevation showing one of the doors of a coke oven and themeans for pilessing the packing medium into `the gap between the doorand the frame,

Fig. 2, is an elevation side of the door,

Fig. 3, is a sectional plan view taken on the line 3-3 of Fig. 1,

Fig.O 4, is an elevation similar to the one shown in Fig. 1 andillustrating a modification,

Fig. 5, is an elevation looking from the side of the door, and

Fig. 6, is a sectional plan view taken on the line 6 6 of Fig. 4.

In the example shown in Figs. 1 to 3 the front wall v of the oven isbraced by anchors v1 located at opposite sides of the door b. Betweenthe door and the wall of the opening thereof an outwardly flaring gap/w1s formed which provides a seat for a suitable packing medium h runningall around the door The said packing medium is adapted to be pressedinto tight contact with the wall of the gap by means of a frameconsisting of an angle iron z' and U-shaped transverse members l locatedsuitable distances apart, Fig. 1 show ing five of the said members. Theframe z', il is mounted on the door b by means of bracket lc xed to thedoor and permitting a slight movement of the members 1 towards and awayfrom the wall 'v of the oven. On bolts a fixed to the door b bars a1 arerockingly mounted which are adapted to be rocked into position behindinclined lugs 0 in the looking from the 112,770, and in Germany June 16,1925. v

form of angle irons fixed to the anchors v1 for holding the door b inposition. In bores of the said bars clamping screws g are guided whichare adapted for clamping engagement with plates m fixed to the members lso as to impart clamping pressure toy the frame z', 1. As appears fromFigs. 1 and 2 the said plates m project from the members "1 respectivelyupwardly and downwardly at the opposite sides of the doors, and the saidprojecting portions are inclined towards the wall of the oven, thusproviding cam faces for the ends of the screws g when rocking the barsa1 into clamping position. The screws g are adapted to be screwedinwardly more or less for regulating the clamping pressure on the framez', z'l. In some cases I provide the same at their inner ends with shoes'n adapted for sliding engagement with the plates m.

' The bars al are connected with each other by a vertical link d, andthe said link' is formed with teeth d1 engaged by a pinion d2 secured ona shaft which also carries a handwheel d5. The shaft with pinion andhandwheel is mounted in a slide d8 guided on the link d and the slide isconnected to one of the bolts a by a swinging link d4. In this way thepinion is .retained in contact with the rack teeth on the link d as thelink swings in the oscillating movement of the bars a1.

The operation of the apparatus is as follows: For fixing the door inposition the hand wheel d5 is turned in a direction for rocking the barsal into the horizontal positions shown in Fig. l as has been indicatedin the said figure by the arrow Thus the said bars engage with theirouter ends the lugs c and force the door b inwardly. Further, the boltsg engage the inclined cam plates m thus forcing the packing medium hinto the gap fw, the clamping pressure being regulated once for all byscrewing the screws g more or less inwardly.

In Figs. 4 to 6 I have shown a modification in which the frame z' forpressing the packing medium into the gap w is acted upon by togglejoints connected to a common operating mechanism. The construction ofthe oven and the door is the same as has been described with referencetoFigs. 1 to 3, and the same letters of reference have been used toindicate corresponding parts. But the door is held in position by meansseparate from the means for forcing the packing medium into the gap, andany known or preferred means may be used for holding the door inposition. v

The frame for forcing the packing medium 71, into the gap w comprisesonly the angle iron z' bent into rect-angular form. At suitabledistances apart brackets 0 are secured to the frame vf and the saidbrackets are acted upon by toggle joints consisting of links p1 and p2,the links p1 being rockingly mounted on pins p3 mounted in lugs b1provided on the door b. The links p1 are formed with extensions p4. Thesaid extensions are connected in pairs to transverse rods 1, and all therods are connected with each other by a link s formed at its middle witha screw-threaded portion t. The said screw-threaded portion is engagedby a hand wheel u the hub of which is held in position between eyes 'alfixed to the door b.

For holding the door in position transverse bars y are rockingly mountedon the door and adapted to be rocked into locking position at the rearof the inclined lugs y1 fixed to the anchors ful, the operation of thesaid bars y being indicated in Fig. 4 by showing one of the barsrespectively in full and broken lines.-

rlhe operation of the apparatus is as follows: The door is iii-st fixedlin position by means of the bars y, in which position the framez' islocated in front of the packing medium 71,. Now the hand wheel u isrotated in a direction for pulling the link s downwardly in F ig. l, sothat the links p1, p4 are rocked more or less into positionperpendicular to the door b. rllhereby the frame z' is forced inwardlyand on the packing me- -dium 7i.

`While in describing the invention reference has been made to particularexamples embodying the same l wish it to be understood that my inventionis not limited to the constructions shown in the drawings, and thatvarious changes may be made in the general arrangement bf the apparatusand the construction of its parts without departing from the invention.
